Abstract:
Objective:To evaluate the safety and effectiveness of robot-assisted coronary artery bypass(RACAB).Methods:We retrospectively analyzed the clinical outcomes from 252 consecutive patients who underwent RACAB in our center between April 2021 and August 2023. The internal mammary artery(IMA) was harvested using the skeletonized technique with the assistance of the robotic system. Then, graft-to-target vessel anastomoses were performed via a 4-6 cm left fifth intercostal thoracotomy. Coronary angiography or coronary CTA was routinely performed before discharge.Results:149 patients(59.1%) underwent multi-vessel coronary bypass. 140 patients(55.6%) underwent total arterial bypass grafting, with 131 patients(52.0%) undergoing RACAB with in situ bilateral IMA. IMA harvesting failed in 6 patients(1.6%). One patient(0.4%) was assisted by extracorporeal circulation, and 5 patients(2.0%) underwent re-thoracotomy postoperatively. The patency rate of grafts was 96.6%(449/465). The 12-month and 24-month survival rate were 97.8% and 96.5% respectively; The 12-month and 24-month MACCE-free survival rate were 95.2% and 92.6%, respectively.Conclusion:RACAB is safe and feasible. With the assistance of the robotic system, in situ bilateral IMA can be obtained and bypassed to all target vessels territory. Extended follow-up is warranted.
